Description

Rectangular tube insert 20×40 mm, black

Black polyethylene rectangular tube insert with a flat flange and three ribs on the internal section
Black polyethylene rectangular tube insert with a flat flange and three ribs on the internal section

The rectangular tube insert is a practical finishing component for closing the open ends of steel and aluminium profiles. It gives the structure a neat finish and protects the inside of the profile from dirt and debris.

The insert is made of polyethylene. The flat external flange covers the edge of the profile, while the ribbed internal section fits inside it. Inserts of this type are pressed into the open end of the profile, with the ribs holding them in place.

Applications

  • Finishing the ends of rectangular profiles in load-bearing structures and frames
  • Protecting open profile ends from the ingress of dirt and debris
  • Providing a neat finish for structural components where the profile edge is visible
  • Complementing assembly kits and support structures made from hollow sections

The dark colour of the insert complements dark profiles and structures, while polyethylene is a material commonly used for products of this type. The insert is sold individually, allowing the quantity to be matched precisely to the number of profile ends to be closed.

Selection and installation

When selecting an insert for a hollow section, check that it is compatible with the profile dimensions and wall thickness. A correctly sized insert sits evenly in the profile, with the flange flush against its edge.

To install, press the insert into the clean, degreased end of the profile. Detailed dimensions are provided in the specification tables below, making it easier to plan an order for multiple profiles in a single project.
